In the new report, in sections on Medicare enrollee LTC data, the CDC says 9% of the 45 million U.S. residents enrolled in Medicare in 2007 reporting using an LTC facility at some point during the previous 12 months, up from 8.9% in 2006.

Medicare enrollees classified as residing in LTC facilities spent an average of $43,253 on facility room and board in 2007, up 9.9% from the 2006 average.

The facility total includes spending on enrollees who used an LTC facility for a short period or for just part of the year, the CDC notes.

Officials divide people with disabilities into groups based on how many limits on "activities of daily living" (ADLs) they face. The ADLs used to create the government statistics are bathingor showering, dressing, getting into or out of bed or a chair, using the toilet, and eating.

The percentage of Medicare enrollees facing limits on 3 or more ADLs held steady at about 13% for disabled enrollees under age 65; fell to 3.6%, from 4.2%, for enrollees ages 65 to 74; held steady at a little less than 10% for enrollees ages 75 to 84; and increased to 26.5%, from 25.8%, for enrollees ages 85 and older.
